Present work deals with the extended applicability of the in situ generated supported silicomolybdic heteropolyanions from the sol-gel synthesized MoO3/SiO2 catalyst for the acetylation of glycerol. The best results were obtained at 118°C using a glycerol: AcOH molar ratio of 1:10 with 100% glycerol conversion in 2 hr and 76% selectivity for triacetin when the reaction was continued for 20 hr.
